2 Claims.

This invention relates to a governor mainly designed for controlling the speed of an internal combustion engine, the general object of the invention being to provide a governor which is 5 very sensitive and which can be manufactured to sell at low cost and which can easily be repaired when damaged.

This invention also consists in certain other` features of construction and in the combination and arrangement of several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specically pointed out in the appended claims.

In describing the invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in Which:-

Figure 1 is a top plan view of the governor showing it in use for controlling the speed of an internal combustion engine.

Figure 2 is a side View of the governor with parts in section.

Figure 3 is a longitudinal sectional view through the front part of the governor and showing how the same is connected to the lever.

Figure 4 is a section on the line 4-4 of Figure 1.

Figure 5 is a section on the line 5 5 of Figure 2.

Figure 6 is a section on the line 6-6 of Figure 1.

Figure '7 is a fragmentary view looking toward the front of the governor.

In these drawings, the numeral I indicates the shaft of the governor which has its inner or rear end threaded into a shaft Il of the motor M, the forward end of the shaft l0 being of rectangular shape in cross section as shown at lil and this part has a sliding fit in a socket i2, of similar shape in crossl section, in a member I3. A strap lll of leather or the like has a hole in its central portion through which the inner portion of the shaft lli passes and this hole carrying par of the strip is held on the shaft by the nuts i4 and l threaded on the shaft with a Washer l5 passing between the hole carrying part of the strip and the nut l5 as shown in Figure 5. The nut ma is of rectangular shape so that the two portions of the strap or strip extending from the part carrying the hole therein, will be caused to assume the parallel position shown in Figures l, 3 and 5. The ends of the strap or strip are pressed around the enlarged part I3' at the inner end of the part i3 and a clamping band I1 is passed around the two end portions Hi', as shown in Figure 4 for fastening said end portions to said part I3. A Weight i3 is connected to each parallel portion of the strap by a bolt and nut shown generally at I 9.

Thus it will be seen that when the shaft iii is rotated by the shaft il at a predetermined speed the weights would swing outwardly and thus cause the parallel portions of the strap or strip to bow and thus exert a pull upon the member i3 Which slides said member on the front end of the shaft it.

This member i3 has a socket 2l! in its front end for receiving the inner end of the pin 2i, the pin being held in the socket by a cotter pin 22 and the pin 2i passes through a hole in a circular part 23 of a lever 2li which is pivoted at 25 to a leg 26 fastened to the front part of the motor. A longer leg 2l is fastened to the front part of the motor and has a slot 28 therein through which the lever passes and this leg 2l has a bent part 29 at its front end for receiving the eye bolt 30 to Which a spring 3l is connected adapted to be connected to the throttle valve of the motor so that the operation of the governor will regulate the valve and thus keep the speed of the motor at the desired speed.

As before stated the u se of the leather strap lll as a part of the governor makes the governor inexpensive to manufacture and this strap can be easily replaced by a new one when worn or damaged and the strap makes the governor very sensitive It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction and arrangement of the and in the combination several parts, provided that such changes fall within the scope of the appended claims.

What is claimed is:-

l. A governor of the class described comprising a shaft, a exible rial having a hole in which the shaft passes, nuts the strap to the necting said portion of the other portions of the strap of non-metallic mateits central portion through on the shaft for conshaft, strap extending parallel to the shaft, a member slidably arranged on the shaft, a clamp for conn ecting the ends of the strap to the sliding member, a lever, means for connecting an intermediate part of the lever to the sliding member, and spring means for holding the lever in a position with the sliding member in outward position with the parallel portions of the straps taut and means for connecting the lever to the member which is to be governed.

2. A governor of the class described comprising a shaft, a exible strap having an opening in its central portion through which the shaft passes, nuts on the shaft for connecting said portion of the strap to the shaft, the other portions of the strap extending in parallel relation, a member slidably arranged on the shaft, a clamp for connecting the ends of the strap to the sliding member, a lever, means for connecting an intermediate portion of the lever to the sliding member, an elongated arm anchored at one end and provided with a lateral portion at its free end disposed in the general longitudinal direction of the lever and having an opening therein, a rod disposed through the said opening of the lateral portion and being threaded and provided with a nut and a spring having one end connected to the threaded rod and the other end to the lever for holding the lever in a position with the sliding member in outward position.
